Slovenia's capital and largest city also happens to be one of Europe's greenest and most liveable capitals. Car traffic is restricted in the centre, leaving the leafy banks of the emerald-green Ljubljanica River, which flows through the city's heart, free for pedestrians and cyclists. In summer, cafes set up terrace seating along the river, lending the feel of a perpetual street party. Slovenia's master of early-modern, minimalist design, Jože Plečnik, graced Ljubljana with beautiful alabaster bridges and baubles, pylons and pyramids that are both elegant and playful. Attractive cities are often described as 'jewel boxes', but here the name really fits. The city's 64,000 students support an active clubbing and cultural scene, and the museums, hotels and restaurants are among the best in the country.
